For a data set of weights​ (pounds) and highway fuel consumption amounts​ (mpg) of seven types of​ automobile, the linear correlation coefficient is found and the​ P-value is 0.035. Write a statement that interprets the​ P-value and includes a conclusion about linear correlation. The​ P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is_____________ which is____________ so there_______________ sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles.

Answer:

The​ P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is__3.5%___ which is___significant_(at α=0.05)_ so there _is_ sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles.

Step-by-step explanation:

Correlation coefficient shows the relation between the weights and highway fuel consumption amounts of seven types of automobile.

P-value states the significance of this relationship. If the p-value is lower than a significance level (for example 0.05) then the relation is said to be significant.

The complete statement is:

The​ P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 3.5% which is low so there is sufficient evidence to conclude that there is a linear correlation between weight and highway fuel consumption in automobiles.

The p-value is given as:

[tex]p =0.035[/tex]

Express as percentage

[tex]p =3.5\%[/tex]

This means that the probability that the linear correlation coefficient is at least as extreme is 3.5%.

From the z-table, we have:

[tex]z =1.81[/tex], when the p-value is 0.035

This value of z-score is low, compared to the percentage of the scores have a z-score of between -1 and 1.

So, the p-value implies that it is likely that there is a linear correlation between the variables.

Hence, the texts that complete the three blanks are: "3.5%", "low" and "is"
